fix(console): allow Ollama custom model validation

[arimu1]

Summary

• Detect Ollama endpoints during custom model validation (explicit ollama provider or default port :11434 / hostname containing ollama)
• Use a dedicated validation path: accept OpenAI-compatible chat responses without a usage field (Ollama often omits it)
• Allow private/local endpoint addresses for Ollama by wiring the existing SsrfProperties.blockPrivate flag (previously unused) instead of rejecting loopback/LAN URLs by default

Fixes #1551

Fixes #1551

Changes

• ModelService.resolveValidationProvider() infers Ollama from provider/endpoint and routes to relaxed response + SSRF rules
• ModelService.isValidModelResponse() accepts Ollama replies with choices only (no usage required)
• ModelService.buildModelApiUrlNew() sets blockPrivate=false for Ollama endpoints
• SsrfParamGuard honors blockPrivate: when false, only explicit IP blacklist applies (not default private-network denial)
• Regression tests for Ollama response without usage and localhost :11434 URL building

Testing

• Existing tests pass (CI — local env lacks Java 21)
• New tests added (if applicable)
• Manual testing completed (code-path / unit-test design review against maintainer triage in [BUG] can not add custom model of ollama #1551)

Added:

• ModelServiceTest.testValidateModel_ollamaResponseWithoutUsage_success
• ModelServiceTest.buildModelApiUrlAllowsPrivateIpForOllamaEndpoint

Prove-it (bug on current main):

1. OpenAI-compat check requires usage — see ModelService.isValidModelResponse() and existing testValidateModel_responseNotCompatible_throws which asserts missing usage is rejected.
2. Private IP SSRF — see existing buildModelApiUrlRejectsPrivateIpWhenBlacklistIsEmpty which asserts http://192.168.x is rejected even with empty blacklist; Ollama on 127.0.0.1:11434 hit the same path.
